Product Details
NSK 30BD40DF2 Automotive A/C Compressor Bearing – Precision Engineered for Reliability
| Description | Key Detail |
|---|---|
| Core Application | OE-replacement bearing for air conditioning compressors in Forland 2000/3000, Nissan, Kreisler, Ford & Mazda vehicles |
| Dimension (mm) | 40 × 62 × 24 — exact match for OEM mounting and sealing |
| Bearing Type | Double-row radial deep groove ball bearing — optimized for combined radial loads & high-speed rotation |
| Material & Hardness | High-purity JIS SUJ2 bearing steel (equivalent to AISI 52100), hardened to HRC 60–64 |
| Precision Grade | P0 (ABEC-1) standard; optional P6/P5 available — ensures ultra-low vibration & noise (<28 dB) |
| Lubrication Ready | Pre-filled with NSK ALC-2 or equivalent low-temperature, high-stability grease — extends service life by 30% vs. generic alternatives |
| Quality Assurance | 100% dimensional inspection, dynamic load testing, and clean-room assembly — compliant with ISO 9001 & IATF 16949 |
| Competitive Edge | Superior cage design (polyamide-reinforced) reduces friction vs. stamped steel cages in budget brands |
| Real-World Performance | Rated L10 life ≥ 12,000 hrs at 5,000 rpm — validated across 500k+ units in field use |
| FAQ: Why no seal replacement needed? | Integrated double-lip nitrile rubber seal (NBR) with dust lip prevents contamination ingress — no retrofitting required |
